Bob Rock it the owner of Lone Peak Productions and I'm the lead editor.
One thing I did notice, the companies names are not in alphabetical order...what is the criteria for the order the companies are listed in?

They are ordered by rating primarily and then date added secondarily. The rating primarily is based on whether they are a leader or not at this point. I'm sure more rating abilities/mechanisms will be added in the future for people to vote on which services are beneficial and which are not but this has not been built yet.

In someone's profile you can see their most recent post. Have you considered adding their most recent comments. I think you could learn a lot about a person by what types of comments they leave and you would be able to quickly see what they like or dislike for that matter.

Yea - It's a good thought and will be added in the future. We've just begun adding separate profile pages for different breakouts of users activity. The first breakout is going to be all the users tagged posts and posts that have been tagged, this is built and will be implemented once it is fully ironed. Comments would be a good next step as well.
